The TC4511BP is a CMOS BCD-to-7 Segment Latch/Decoder/Driver manufactured by Toshiba Semiconductor and Storage. This integrated circuit is designed to convert Binary Coded Decimal (BCD) input into a format suitable for driving 7-segment displays. It incorporates a latch function, allowing it to hold the input data. The decoder section transforms the BCD input into the appropriate signals for the 7 segments of the display. Additionally, it includes a driver stage to provide sufficient current to illuminate the segments of the LED or LCD display.

Additional Details

The TC4511BP typically comes in a 16-pin DIP (Dual In-Line Package). The input is a 4-bit BCD code, and the outputs are the 7 segment drive signals (a, b, c, d, e, f, g). Several control inputs are available, including a Latch Enable (LE) input, a Blanking Input (BI), and a Lamp Test (LT) input. The LE input controls the latch function, the BI input blanks the display, and the LT input tests all segments by turning them on. The operating temperature range is typically -40°C to +85°C. The power dissipation is relatively low due to the CMOS technology.
